This module can be used for portable instrumentation, consumer goods, battery monitoring, temperature measurement, factory automation and process controls
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C.
The chip can be configured as 4 single-ended input channels, or two differential channels.
As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers.
